| Outline of Final Research Achievements |
I obtained a degree formula for Grassmann bundles associated to vector bundles on non-singular projective varieties, as a joint work with Tomohide TERASOMA. I wrote a joint paper with TERASOMA for the resuls, and published it in a scientific journal. I also studied the higher Gauss maps for projective varieties, and obtained a degree formula for the images of higher Gauss maps of Veronese varieties, which yields a generalization of the classical formula by Boole. I wrote a paper for the result of a continued work on the linear degeneration of tangentially degenerate curves, and published it in a scientific journal.
